[RESOLVED] extracting array elements as list of values

jwagner

So, here I go with my tasty code...

//array holds cake name and price
$cakes = array('cherry' => 3.49 , 'cinnamon' => 1.49); //tasty, ha?


$new_cakes = array('chocolate' => 1.99 ,
                 'cheese' => 3.99,
                 'vanilla' => 2.49); //yup, new cakes, freshly baked...

array_push($cakes, $new_cakes); //pushing cakes? watch out not to melt the chocolate

Now, printing this array would produce:

Array
(
    [cherry] => 3.49
    [cinnamon] => 1.49
    [0] => Array
        (
            [chocolate] => 1.99
            [cheese] => 3.99
            [vanilla] => 2.49
        )

)

Of course, that is not what I want. I need all my cakes in one basket... The problem is of course that I am pushing the $new_cakes array itself onto the first array, instead of pushing the elements in the array.

So, in an effort to solve my problem, I thought of using it like this:

array_push($cakes, extract($new_cakes)); //thinkin' extract would insert all elements...

But, yeah, does not work.

My mind tricked me into another funny idea which was also a big failure...

array_push($cakes, list() = $new_cakes); //it's your chance to laugh at me (n00b) now...

Q: any way to extract array elements to a list of values so they can all be passed as a row of parameters in a function?

Thanks guys

I think you are looking for array_merge

As far as I know array_merge returns an array, and that is not what I am looking for.

What I want is to take the array and get a list of results that can be passed to a function.

Example:

Let's say I have this array:

$my_array = array('one', 'two', 'three');

Now, I need to call this function:

my_function(var1, var2, var3...)

So I want to extract all the array elements and pass them to the function, in a way that the result should be:

'one', 'two', 'three'

IMO that seems like more work that you need. If you just need to combine two arrays with the keys/values then there are a couple different ways to do this. Then just pass the new, complete array to your function.

//array holds cake name and price
$cakes = array('cherry' => 3.49 , 'cinnamon' => 1.49); //tasty, ha?


$new_cakes = array('chocolate' => 1.99 ,
                 'cheese' => 3.99,
                 'vanilla' => 2.49); //yup, new cakes, freshly baked...

$cakes = array_merge($cakes, $new_cakes);

unset($new_cakes); // not needed anymore..

my_function($cakes);

function my_function($cakes) {
    foreach ($cakes as $type => $price) {
        // whatever here...
    }
}

OR go with this instead of array_merge()

$cakes = $cakes + $new_cakes;

Thanks very much. I really appreciate it.
